    Abstract

    Today the times and technological advances require no exceptionin the field of building materials. Lots of research has been done on the building material. The material research not only on the determination of the exact composition of the mixture of materials, but also look for other alternatives such as the addition of additives and the replacement of a component with other components. The chemical reaction between cement and water to produce compounds that accompanied the release of heat. These conditions contain a great risk to the shrinkage of concrete that results in concrete cracks, so the need for improvement of one of them by the addition of volcanic ash and aluminum fibers. The aim of this study was to determine how much influence the use of volcanic ash and aluminum fibers pressed against a strong capacity and modulus of elasticity of concrete produced with a variety of pre-determined mix. Research carried out by the laboratory of experimental research. In this study using the test specimen in the form of a cylinder with a diameter of 150 mm and a height of 300 mm for the strength test and modulus of elasticity prodded with each additional levels of volcanic ash at 0% and 20% and aluminum fibers at 0%, 0.5%, 1% and 1.5%. The testing process includes testing of materials, urged strength test, and test the elasticity modulus. Concrete testing results are as follows where the value of compressive strength normal concrete with added fiber materials aluminum and ash in this study reached the highest value on the fiber content of 1% aluminum and 20% of volcanic ash with the strong urge of 23,44 MPa or increases by 12,90 % stronger than normal concrete persisted. Then for testing the modulus of elasticity reaches the value of the highest value on the fiber content of 1% aluminum and 20% of volcanic ash with the modulus of elasticity of 22869,26 MPa. This suggests that an increase of 7,08 % against the normal concrete.. Keywords: compressive strength, modulus of elasticity, normal concrete, volcanic ash, aluminum fiber
